Portable fuel transfer unit

ABSTRACT

A portable fuel transfer unit comprising a plurality of functional elements, such as an electric pump connected to the intake with a flexible hose provided at the end with an adapted filter with a one-way valve and to the delivery with a flexible hose provided with a dispensing nozzle at its end; the unit comprises a shell which is divided into two detachably connected sections and has the electric pump fixed to a first section and is adapted to contain all of the functional elements when the two sections are assembled.

BACKGROUND OF THE INVENTION

It is known that there are portable units adapted to transfer fuel drawn from a fixed storage tank and sent to the tank of a means of locomotion used in the most disparate sectors, such as for example building yards, boating, or even in agriculture.

These units comprise an electric pump provided with flexible hoses at the intake and delivery: at the end of the hose that is connected to the intake there is a device which comprises a filter and a one-way valve designed to be inserted in the fixed storage tank, and at the end of the hose that is connected to the delivery there is a nozzle for dispensing the fuel to the tank of the means of locomotion.

The conventional transfer units suffer some drawbacks such as for example less than ideal operating modes, and further the possibility that leaks into the environment of residues of the fuel that has remained inside said units may occur.

SUMMARY OF THE INVENTION

The aim of the present invention is to provide a portable unit that offers maximum convenience in management and is able to guarantee reliability against any possibility of environmental pollution.

This aim and other objects which will become better apparent hereinafter are achieved by a portable fuel transfer unit, according to the invention, characterized in that it comprises the features according to the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS

Further characteristics and advantages will become better apparent from the description of an embodiment of the portable fuel transfer unit according to the invention, illustrated in the accompanying drawings, wherein:

FIG. 1 is a perspective view of the containment shell in the closed condition;

FIG. 2 is a perspective view of the containment shell in the open condition and with the functional elements contained therein still arranged as they were in the condition in which the shell was closed;

FIG. 3 is a perspective view of the functional elements extracted from the open shell.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the figures, the reference numeral 1 generally designates the containment shell formed by two sections 2 and 3, which, when such sections are connected to provide the closed shell condition as shown in FIG. 1, is capable of containing all the functional elements that will be described hereafter, arranged as shown in FIG. 2.

Such functional elements of the unit comprise an electric pump 4, which is powered by means of a line that is connected to terminal clamps 4 a, 4 b and is fixed to the first section 2 of the shell, and is connected to the intake directly with a flexible hose 5 provided at the end of a device 5 a, which comprises a filter and a one-way valve and is designed to be inserted in a fixed storage tank.

Moreover a rigid tube 6 is fixed to the delivery of the electric pump 4, for connection to a filter head 7, which is fixed to the first section 2 of the shell and from which a flexible hose 8 extends and supports, at its end, a nozzle 9 for dispensing the fuel to the tank of a means of locomotion, with a coupling 9 a.

With the shell 1 closed so as to contain all the functional elements, extremely easy conditions for transporting the unit are provided, and moreover any possibility of environmental pollution and of contact of the functional elements with foreign matter, such as for example dust or dirt, that might damage them is prevented.

Where it is necessary to transfer fuel, it is sufficient to detach the second section 3, which acts as a cover, from the first section 2 of the shell, and the management of the functional elements is entirely easy, as shown in FIG. 3.

In the practical embodiment of the invention, all the details may be replaced with other technically equivalent elements.
